ðŸ›Ąïļ Emergency Veterinary Preparedness Checklist

Small animals, birds, and exotic reptiles have a natural biological instinct to hide their illnesses to avoid attracting predators in the wild. By the time they show obvious signs of mouth rot (infectious stomatitis), they may have been sick for several days. Use this quick checklist to protect your pet:

📞 1. Call Your Vet Clinic First Always call the clinic while you are on your way. This lets the veterinary team prepare their oxygen tanks, incubators, or species-specific medication before you walk through the door.
🚗 2. Secure and Warm Transport Transport small pets in a secure, well-ventilated carrier lined with fleece (avoid loose-threaded towels which can trap claws). For reptiles and weak animals, place a warm (not hot) water bottle wrapped in a cloth inside the carrier.
📝 3. Gather Crucial Timeline Details Be prepared to tell the vet exactly: (a) when the symptom started, (b) their recent eating habits, (c) if they have had healthy poops, and (d) any access to house plants, chemicals, or human foods.
